You can measure it, but you can't calculate it. That's why the resistance of a
resistor is always printed on it, either in numbers or in color bands. Without that
marking, the resistor is pretty useless. If it accidentally missed being marked
during manufacture, it would be either discarded, or sold surplus for bubkes.
What else can I help you with?
How is electrical resistance calculated?
Resistance (Ohms) = Potential Difference (Voltage) / Current (Amps)
What is tower footing resistance?
footing resistance is that resistance which could not harm human body while touching tower...and it is calculated by earth resistance tester
In physics what is the use of meter bridge?
A meter bridge is used to measure an unknown electrical resistance by comparing it with a known resistance. It works on the principle of Wheatstone bridge. By balancing the bridge circuit, the value of the unknown resistance can be calculated accurately.
How do you measure the resistance in a parallel circuit?
You have to measure the voltage, and the current. The resistance is then calculated by using Ohm's Law.
Does measured value of resistance match the calculate value of resistance?

How can resistance be calculated by?
Resistance can be calculated using Ohm's Law, which states that resistance (R) is equal to the voltage (V) across a component divided by the current (I) flowing through it: ( R = \frac{V}{I} ). Additionally, in a circuit with multiple resistors, total resistance can be calculated using series and parallel formulas. For resistors in series, the total resistance is the sum of individual resistances, while for resistors in parallel, the total resistance can be found using the formula ( \frac{1}{R_{total}} = \frac{1}{R_1} + \frac{1}{R_2} + \ldots ).
What will be the voltage drop with a load of 42amps with?
without knowing resistance this cannot be calculated
Is there any difference in measured and calculated value of resistance?
Yes, there may be differences between measured and calculated values of resistance. Measured resistance is obtained through direct measurement using a multimeter or other relevant instruments, while calculated resistance is determined using Ohm's Law based on the circuit components. Factors such as temperature, component tolerances, and measurement errors can lead to discrepancies between the two values.
Four 50 ohms are connected in series calculate the current in the circuit?
The series resistance is 4 x 50 = 200 Ohms. You would need additional information to get the current; usually this is calculated from the voltage. current = voltage / resistance.The series resistance is 4 x 50 = 200 Ohms. You would need additional information to get the current; usually this is calculated from the voltage. current = voltage / resistance.The series resistance is 4 x 50 = 200 Ohms. You would need additional information to get the current; usually this is calculated from the voltage. current = voltage / resistance.The series resistance is 4 x 50 = 200 Ohms.
